Fuzzy Database Techniques During Corona Epidemic

Abstract

The databases are widely used in public information systems, which, in turn, use software tools for safe and secure data processing called Database Management System (DBMS), which ensure the connection between the user level or the programmer and the level of representation of physical or physical data to store and retrieve data. Database applications have become widely used because of the tremendous development of database technologies, most database applications are based on relational database model and are advantageous to the query language, the Structured Query Language (SQL) is a logic-based binary so they do not represent the real reality and overlook an important aspect of truth.
This paper presents Logic Fuzzy Techniques in SQL Query System Design Using Delphi programming language and Oracle8 database management system in relational databases supports Fuzzy logic, so this paper will explain common language systems that have the ability to deal with big data -especially the fuzzy database that are currently being used to combat the Corona epidemic.
